Continuous Prairie points

Towards the end of 2011 one of my beginner quilters (Jolita, this is for you) asked me how continuous prairie points are made.  Their group however grew up and cut the apron strings and now don't come together at my house anymore.  I however still owe Jolita an answer and this is for anyone else who ever wondered about these.

I searched the internet to find the best possible explanation and it turned out to be this video tutorial by Fave Quilts.

Hope this helps.
